Abstract
Official abstract text for this publication.
A compact motor-drive unit wherein each component can be stably fixed to the unit. A motor-drive unit has a plurality of substrates each having a circuit for driving a motor; semiconductor devices mounted on the respective substrates; at least one smoothing capacitor mounted on at least one of the substrates; and a heat radiator having a heat-transferring surface adjacent to the semiconductors. The smoothing capacitor is positioned within a swept area formed by moving the first substrate arranged generally parallel to a base surface, in a counter-front direction, so that the smoothing capacitor is separated from the first substrate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor-drive unit comprising: a first substrate and a second substrate wherein a circuit for driving a motor is divided and divided sections of the circuit are formed on the first and second substrates; a connecting part which connects the first and second substrates so that the first and second substrates intersect with each other; a semiconductor device mounted on each of the first and second substrates; a heat radiator having a first heat-tr…
